BUSH-HAMMER.

SPECIFICATION forming part of Letters Patent No. 358,090, dated February22, 1887. Application filed September 27, 1886. Serial No; 214,613. (Nomodel.)

To 60% whom it may concern:

Be it known that I, HUMPHREY TOOMEY, a citizen of the United States,residing at Leetes Island, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inBush-Hammers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to the class of bush or stone hammers which areprovided with detachable blades, and has for its object to greatlysimplify, cheapcn, and at the same time improve the construction bymaking the head of the hammer in a single piece. XVith these ends inview I have devised the simple and novel construction of which thefollowing description, in connection with the accompanying drawing, is aspecification, numbers being used to indicate the several parts of thedevice.

The drawing is a perspective of my improved hammer complete, the bladesbeing removed at one end and shown in position at the other.

1 denotes the body of the hammer, 2 the hole to receive the handle, and3 openings at opposite ends of the body to receive the blades 4.

5 denotes holes extending entirely through the body from side to side,and 6 slots extending from the bottoms of openings 3 into said holes,the object of these holes and slots being to give the side pieces, if,sufficient spring to enable them to grasp and hold the blades firmlywhen tightened up, and to spring back sufiiciently so that they may bereadily taken out when loosened up.

The blades may be held in position in any suitable manner. I preferably,however, provide holes 8 through the side pieces, in line with eachother, which also register with holes (not shown) through the bases ofthe blades, bolts 9 being passed through the opposite side pieces andthe blades and tightened up by nuts in the usual manner.

Hereto fore the changing of the blades in this class of hammers has beena matter of considerable trouble and inconvenience, owing to the factthat the body of the hammer was made in two or three parts. My improvedconstruc tion, however, enables me to make the body of the hammer andthe side pieces from one piece of metal, and at the same time to retainample spring in the side pieces. I thus produce a much neaterlookinghammer, while at the same time I cheapen the construction and greatlysimplify the mode of operation.

It will of course be understood that the details of construction may beconsiderably varied without departing from the spirit of my invention.

I claim The body having blade-openings 3, holes 5, and slot 6, leadingfrom the base of said openings to said holes, in combination with aseries of blades and bolts, 9, whereby said blades are clamped in theopenings.

In testimony whereof I afiix my signature in presence of two witnesses.

HUMPHR-EY TOOMEY.
